Integration Service follows instructions coded into Update
Strategy and Custom transformations within the session
mapping to determine how to flag rows for insert, delete,
update, or reject.
If the mapping for the session contains an Update Strategy
transformation, this field is marked Data Driven by
default.
If you do not choose Data Driven when a mapping contains an
Update Strategy or Custom transformation, the Workflow
Manager displays a warning.
